Below are sample questions representative of the exercises included on this worksheet and related 4.63 Laboratory Safety and Symbols skill assessments:

Problem 1Difficulty: Mastery
Look at the planned lab scene with numbered stations. Which action list follows the posted symbols in the correct order from start to finish?
APick up the warm cup first, then look for goggles, then throw any broken glass into regular trash, and leave the sink wet.
BPut on goggles at Station 1, move warm items carefully at Station 2, report broken glass at Station 3, and dry the sink area at Station 4.
